Rosey finds & fixes errors in your most important documents
Roseyv1.1.0Version updatev1.1.0Jun 19, 2026With AI, generating content has scaled far faster than our capacity to verify it. For the work that really matters, we've unwittingly shifted from authors to fact-checkers, searching for an unknown number of hard-to-find errors.
Unfortunately, we can’t trust AI to QA AI – see my recent posts about why (worth a look if you missed them).
Rosey is different. It indexes your trusted sources of truth into a relational fact database, then verifies your draft with our own independent Math & Logic Engine that deterministically reconstructs every number, date, and calculation. Because this isn’t a black box, Rosey shows its work and gives you direct access to the specific passages and numbers from your source material used to verify each claim.
It works where you work — directly in your chat, tightly integrated into MS Word, or embedded in your agentic workflows.
- Full MS Word integration available in the MS AppSource Add-in marketplace.
- MCP integration for chats and agentic workflows
- Accurate file viewer that takes you right to your citations
- Fact-checking and expert persona review to pressure test your document from the angles that matter
Overview
Rosey independently verifies documents that AI helped write, catching the wrong numbers, unsupported claims, and omissions LLMs leave behind.It works inside Word, returning cited and traceable tracked changes, and catches 3.5x the errors that frontier LLMs find. An MCP integration brings the same fact-checking and resulting trust into your chats and agentic workflows.
Key Features
- Purpose-built For Verification, Not Generation. Rosey Doesn't Write Your Document Better — It Independently Checks The One You Have, The Way An Llm Can't.
- Every Finding Is Cited And Traceable. Each Flag Links Back To The Ground-truth Source, So Everything Is Autidable.
- A Real Math & Logic Engine. Numerical And Logical Consistency Are Checked Deterministically, Not Left To A Language Model's Approximation.
- Expert Persona Reviewers. Beyond Accuracy, Rosey Reviews Through Role-based Lenses (cfo, Adversarial Analyst, Operating Partner) To Catch Omissions And Weaknesses, Not Just Outright Errors.
- Mcp Integration For Agentic Workflows. Run Fact-checking Headless, As A Step Inside Automated Pipelines — Not Just In The Ui.
- Native To Word, Delivered As Tracked Changes. No Copy-paste, No New Tool To Learn; Edits Land In The Format Reviewers Already Work In.
